Product Guide (withdrawn product)

The Flex System™ CN4022 2-port 10Gb Converged Adapter is a dual-port 10 Gigabit Ethernet network

adapter that supports Ethernet, FCoE, and iSCSI protocols as standard. The EN4172 2-port 10Gb Ethernet

Adapter is a similar adapter that supports Ethernet protocols. Both adapters also support virtual network

interface controller (vNIC) capability, which helps clients to reduce cost and complexity. These adapters are

based on the Broadcom BCM57840 controller.

The CN4022 and EN4172 are shown in the following figure. The adapters are physically identical.

Figure 1. Flex System CN4022 2-port 10Gb Converged Adapter and EN4172 2-port 10Gb Ethernet Adapter

Did you know?

The CN4022 is based on the industry-standard PCIe architecture and is ideal for clients who use 10 GbE in

their network infrastructure and who are looking for an entry price point for FCoE or iSCSI capabilities. The

adapter ships standard with support for FCoE and iSCSi and with vNIC features that allow each physical port

of the adapter to be virtualized into four vNICs.
